Act as a seasoned concept artist with 10+ years of experience in dystopian world-building. Create a highly detailed MidJourney image of a post-apocalyptic caravan trekking through a vast, sun-scorched desert. The scene should feature: [a convoy of rusted, jury-rigged vehicles cobbled together from scrap metal], [a group of weary survivors clad in tattered, makeshift armor and gas masks], and [a towering sandstorm looming in the distance, casting an eerie orange glow over the barren landscape]. Include subtle details like: [frayed banners fluttering in the wind], [sun-bleached animal skulls marking the path], and [glowing bioluminescent fungi growing from cracks in the vehicles]. Use a cinematic 16:9 aspect ratio with dramatic lighting to emphasize the harsh, unforgiving atmosphere of this wasteland journey.
